Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed August 1,1905. Serial No. 272,275.

To to whom, if; nuty concern.

Be it known that I, VVAL'rnR B. MANNY, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Stopping and Starting Devices for Motor-Driven Apparatus, of which the following is a specification.

In certain classes of motor-driven machines, as adding-machines, it is desirable that the 1110- tor shall be in motion only when the operator is present and in position to actuate the machine. It has been common to provide such apparatus with stopping and starting devices, as valves or switches, according to the character of motor used; but it has been found in practice that the operators will forget to shift the stopping and starting device on leaving the machine, leaving the motor in operation uselessly for hours at atime. To avoid these objections, I combine the stopping and starting device with the movable seat or support for the operator of the machine, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which Figure l is a side elevation of a Pike adding-machine, showing my improvement. Fig. 2 is a detached sectional view of the stopping and starting device, shown as a switch. Fig. 3 illustrates another form of support for the operator of the machine. Fig. 4 is a view illustrating the arrangement when air or other like motor fluid is used.

The machine A is of any desired character and supported by a table B, which also supports the motor by which the machine is driven. As shown in Fig. 1, the motor is an electric motor deriving its power from a generator G, Which is in a circuit including also the motor, a switch S, and a flexible electric connection a between the motor and switch. The switch is suitably placed upon part of the support provided for the operator of the machine, which support may have either the form of a stool or chair C, as shown in Figs. 1 and 2, or a low platform or stand C, as shown in Fig. 3, and is so constructed and arranged that the weight of the operator will close the circuit. I/Vhile any suitable arrangement may be employed, I have found that shown in Fig.

f. So long as the seat or stand is unoccupied the spring (Z will force out the plug and separate the terminals, so that no energy is transmitted to the motor; but as soon as the operator seats himself or steps upon the stand the terminals are brought in contact and the motor is put in operation. \Vhile this result is automatically effected, it in no way restricts the position or movements of the operator, who can shift the seat or platform to any position and as often as required, an important matter, as it is frequently necessary, in banks for instance, for the operator to frequently leave the machine to consult persons or books or to receive or distribute papers.

In the construction shown in Fig. 4L the seat of the stool is raised by a spring gand is supported upon a bar 70, carrying a rack i, which gears with a pinion j on a valve-stem, the valve being in a casing it, to and from which water or air can flow through the pipes of the flexible connection (0, extending to a water-motor arranged like the electric motor shown in Fig. 2.

It will be understood that when in the claims reference is made to a stool it is intended to describe either the seat or chair on which the operator sits or the platform or raised support on which he stands when operating the machine.

Without limiting myself to the precise construction and arrangement shown, I claim- 1. The combination with a machine and its motor and a movable stool for the operator, of a stopping and starting device arranged upon the stool to be shifted by the presence of the operator, and a flexible connection between said device and the motor, of a character to permit the stool to be shifted to different positions, substantially as set forth.

2. The combination with a machine, its electric motor and a IhOVZtblG stool, of a switch ln testimony whereof I have signed my name upon the stool, a spring separating the ter- 0 this specification in the presence of two subpressed when the stool is occupied, and a flexible connection between the switch and motor, of a character to permit the stool to be shifted to different positions, substantially as set forth.
